ASTM C932-05

Standard Specification for Surface-Applied Bonding Compounds for Exterior Plastering

SCOPE
1.1 This specification covers minimum requirements for exterior surface-applied bonding compounds for improving the adhesion of cementitious material to concrete or other masonry surfaces or any structurally sound surfaces.
1.2 This specification also covers test methods for determining performance requirements and physical properties.
1.3 The values stated in inch-pound units are to be regarded as the standard. The SI metric values given in parentheses are approximate and are provided for information purposes only.
1.4 The following safety hazards caveat pertains only to the test methods described in Sections , , , and in this specification:This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
